✦ Synopsis

The dispersion (ZM) and selectivity (P) indices of several series of chlorinated aromatic compounds, including chlorinated benzenes, anisoles (methoxybenzenes), veratroles (1,2-dimethoxybenzenes), phenyl acetates, benzaldehydes, 2-hydroxybenzaldehydes (salicylaldehydes), 4-hydroxybenzaldehydes and phenols, were determined on low-polarity (SE-30) and polar capillary columns. The effect of the individual substituent groups and of multiple substituents and their positions on the aromatic ring are discussed in terms of the relevant polar interactions. The results are compared with those previously reported for aliphatic and aromatic esters. ' For Part III, see ref. 3.

The division of the retention indices of simple carbonyl-containing compounds into components indicative of apolar and polar interactions is reported. About 200 compounds in 40 homologous series were studied, including simple esters with branching and unsaturation in both the alkyl or alcohol and ac

## Abstract The scope of the principal techniques employed for the analysis of hydrocarbon mixtures is discussed, with emphasis on the analysis of one and two ring aromatic compounds by single column capillary gas chromatography. The paper considers both the column and the selection of the temperat
